Default OS Speed XZ-R .21 13880 Bearing Size Front and Rear
I am just about to upgrade my OS Speed XZ-R with ceramic bearings and I just wanted to check if these were the correct sizes from BOCA.

The sizes are:

Rear ID 14mm x OD 25.4mm x Width 6mm
Front: ID 7mm x OD 19mm x Width 6mm

I can't find in any manual or online the exact sizes to purchase..
